Description

Technical Field

[0001] The invention relates to the field of soil treatment, and in particular to a soil treatment improver spraying device. Background Art

[0002] With the rapid development of industrialization and urbanization, soil pollution and soil fertility decline have become increasingly serious. Factors such as the discharge of industrial waste, excessive use of fertilizers and pesticides in agriculture, and unreasonable land use have led to excessive heavy metals in the soil, soil compaction, and increased salinization. Farmland that has long relied on fertilizers has had its soil structure destroyed and its ability to retain water and fertilizer reduced.

[0003] Soil conditioners can adjust the size and distribution of soil pores. Some conditioners will produce gas during decomposition, thereby increasing the ventilation pores in the soil. At the same time, the fiber components in the conditioners (such as straw, etc.) can form pore channels in the soil, which is conducive to the exchange of air and water, while neutralizing acidic soil, regulating alkaline soil, and improving soil fertility.

[0004] Although the existing mechanical spraying devices have improved efficiency to a certain extent, it is difficult to ensure that the improver is evenly distributed throughout the entire working area when spraying large areas of soil. Common vehicle-mounted spraying equipment, due to the length and angle limitations of the spraying arm, areas close to the spraying source may be sprayed with too much improver, while areas at the edge or far away may not be sprayed enough, resulting in uneven soil improvement effects. In addition, most spraying devices find it difficult to effectively transport improvers into deep soil. During the spraying process, the improver may be offset due to factors such as wind, which will not only reduce the effective utilization rate of the improver, but also pollute the surrounding ecological environment.

[0044] Second embodiment

[0045] Please refer to Figure 4 , Figure 5 and Figure 6 Based on the soil improvement agent spraying device provided in the first embodiment of the present application, the second embodiment of the present application proposes another soil improvement agent spraying device. The second embodiment is only a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0048] The working principle of the soil improvement agent spraying device provided by the present invention is as follows:

[0049] The tractor adjusts the device to descend until the soil-breaking knife 301 touches the ground and penetrates two centimeters into the soil. The soil is broken under the movement of the tractor, and then the bucket 405 scoops up the broken soil. The stirring motor 801 is started, driving the stirring blades 804 on the stirring shaft 803 and the stirring disk 802 to evenly stir the medicine in the medicine box 7, and start spraying and treating the soil.

[0050] Compared with the related art, the soil improvement agent spraying device provided by the present invention has the following beneficial effects:

[0051] Under the action of the soil-breaking mechanism 3, the tractor drives the soil-breaking mechanism 3 to break the soil surface during movement, which is convenient for subsequent soil shoveling and spraying treatment, making the spraying of the agent more effective. The addition of the stirring mechanism 8, when using multiple improvers or needing to mix the improvers with solvents such as water, the stirring and mixing function of the stirring mechanism 8 ensures that the agents are fully and evenly mixed. During the spraying process, especially during long-term operations, it is prevented that some components in the improver may precipitate and clog the nozzle or pipe.

[0052] Third embodiment

[0053] Please refer to Figure 7 , Figure 8 , Fig. 9 and Fig.10 Based on the soil improvement agent spraying device provided in the first embodiment of the present application, the third embodiment of the present application proposes another soil improvement agent spraying device. The third embodiment is only a preferred embodiment of the first embodiment, and the implementation of the third embodiment will not affect the independent implementation of the first embodiment.

[0054] Specifically, the difference of the soil improvement agent spraying device provided in the third embodiment of the present application is that the mounting plate 6 is rotatably mounted with a pushing hydraulic cylinder 15 through a swivel seat, the surface of the slider 502 is fixedly mounted with a push plate 19, the pushing hydraulic cylinder 15 and the push plate 19 are rotatably connected through a swivel seat, the surface of the upper spray frame 505 is fixedly mounted with a transverse slide 17, the transverse slide 17 is slidably connected with a transverse connecting rod 16 through a swivel seat, the transverse connecting rod 16 is connected to the lower spray frame 406 through a swivel seat, the surface of the bracket 1 is fixedly mounted with a transverse slide 18, and the descending hydraulic mounting plate 401 is slidably mounted in the track of the transverse slide 18. A water tank mounting plate 12 is fixedly mounted on one side surface of the mounting plate 6, a shielding and cleaning mechanism 11 is arranged at the bottom of the water tank mounting plate 12, the cleaning mechanism 11 comprises a cover 1103, a hinge 1102 is fixedly mounted on the surface of the cover 1103, the cover 1103 is rotatably connected to the water tank mounting plate 12 via the hinge 1102, a pulling hydraulic rod 1101 is connected between the cover 1103 and the water tank mounting plate 12, and the surface of the cover 1103 is rotatably mounted via a swivel seat There is a push rod 1107, and the push rod 1107 is connected to the lifting frame 1105 through a rotating seat. A lifting telescopic rod 1108 is fixedly installed between the lifting frame 1105 and the mounting plate 6. A pulling telescopic rod 1104 is rotatably connected between the cover 1103 and the upper spray frame 505 through a rotating seat. A spray head 1106 is fixedly installed at the bottom of the lifting frame 1105, and a water tank 13 is fixedly installed on the top of the water tank mounting plate 12. A water pipe 14 is connected between the water tank 13 and the groove. A water leakage notch is opened on the bottom surface of the cover 1103, and a sponge is installed at the water leakage notch of the cover 1103. Baffles are installed on both sides of the cover 1103. The moving distance of the lifting frame 1105 is adapted to the thirty-degree rotation angle of the upper spray frame 505. The edge height of the cover 1103 matches the nozzle length of the upper spray frame 505.

[0055] There are two spray heads 1106, which are respectively installed on both sides of the telescopic rod 1104 to spray the upper spray frame 505 and irrigate the land.

[0056] The working principle of the soil improvement agent spraying device provided by the present invention is as follows:

[0057] After the spraying of the land with the agent is completed, the land needs to be irrigated. At this time, the agent pump 9 no longer supplies the agent, and the water in the water tank 13 is supplied to the shielding and cleaning mechanism 11 through the water pipe 14.

[0058] Compared with the related art, the soil improvement agent spraying device provided by the present invention has the following beneficial effects:

[0059] During chemical treatment, the upper spray frame 505 may be disturbed by external soil, causing the nozzle of the upper spray frame 505 to be blocked, resulting in substandard treatment effect. The shielding and cleaning mechanism 11 will drive the upper spray frame 505 to rotate and clean to prevent the nozzle from being blocked by soil. The land after treatment needs to be properly irrigated, so the shielding and cleaning mechanism 11 can both clean the nozzle and complete the land irrigation, greatly improving the working efficiency of the device.
